The invention relates to a machine for filling cartons with cans. While numerous features of the machine are capable of general application, an important object of the present invention is to provide improved means whereby cans fed in a single line are assembled to form a load of cans comprising a plurality of layers and a. plurality of tiers, so that the entire contents of a full carton are introduced therein at a single operation.

In assembling the cartons "as above outlined and suggested, it has been found desirable to provide a plurality of ways, one over the other,

in order to provide for arranging the load in a. plurality of tiers, and in filling these ways successively, the cans are led at intervals downwardly from themain or top 'way. To this end the 'can supporting elements of the ways are formed with moveable sections which swing downwardly or are otherwise opened after the manner of a gate, transferring the proper number of cans from the upper to the respective iower ways whereby the cans are arranged in iers.

In the preferred form of the machine, to prevent interference with the operation of these gates, the cans or other cylindrical packages are so controlled that after the machine is once primed with cans and ready for operation, a number of cans corresponding to a load or charge is segregated or grouped on the ways, or more particularly on the main or top way, and the group is released when and not until when it is required for the replenishment of the cans in the load-formingmechanism. By this method of operation the complete filling of the ways on the intake side of the load-forming enclosure and consequent interference with the operation of the gates is prevented.

The machine also includes, as a feature of the invention, a system of canstops for grouping and controlling the individual loads of cans ,as thus described, and a series of feelers and detectors whereby the introduction into a carton of a portion of a load, i. e., the delivery of partially fllledcartons is prevented. The machine is also provided with a can feeler controlling the elevator and preventing the choking oi the machine with cans.

The machine further relates to the provision of a rotary drum which receives the empty cartons and presents them in turn to the charge delivery mechanism, dropping each charge in turn into a corresponding carton, eliminating the necessity for a reciprocating plunger in the preferred form of the machine, though'certain ele ments of the machine may be utilized in a plunger machine.

The machine in the preferred form in its operation receives corresponding loads or charges of cans in registration with the cartons, and swings each carton with the corresponding load into a position in which the load overlies the open end of the carton, whereby the load being duly released is introduced into the carton by gravity.

The invention also relateslto a delivery means for the filled cartons whereby the cartons being released from the drum by gravity, are caught by a resiliently or yieldingly supported conveyor which meets the carton at the point of release from the drum and yields downwardly, gradually checking the momentum of the filled carton, so

that the delivery is efiected quietly and without shock or any possibility of injury to the containers.

The invention also includes braking means for the drum, whereby the speed of the drum as it approaches the end of each step in the rotation of the drum is gradually checked and the drum is brought to a stop in receiving and delivering position, and to improved means for holding and controlling the cartons in receiving relation to the drum, and to means for automatically coating the side flaps of the cartons with paste.

In the form of machine shown, the front or receiving end of the machine is provided with improved means for diverting the alternate cans forming two lines containing equal numbers of cans. These two lines of cans are presented to the shelves side by side, the cans of the respective lines being end to end, and they are thus deposited in the cartons as two layers, the cans'being in the preferred arrangement of the invention first progressed immediately after dividing in two lines one over the other.

The dividing mechanism previously in use has consisted of a rocking vane or wedge which not infrequently failed to divert the cans, and at times injured some cans which landed on the point of the vane.

The dividing mechanism shown in connection with the machine of the invention is of an improved'form in that it is more certain in its operation than those previously in use, its operation resulting in a uniform division of the cans which prevents accumulation of an excess of cans in either line with a resulting unequal delivery oi the load and consequent stopping of the machine. This result is attained by increasing
